In order to solve non-linear, parameter time changing, anti-disturb and time-lag problems, a PID control method based on the BP neural network has been presented and applied in the variable pitch wind turbine control system. After analyzing the BP neural network PID control principles, a control system was established. Then the simulation was carried out based on Simulink. Finally, a conclusion was...
Yaw system plays an important role in wind turbine generator because of the direction and intensity of wind is time-varying. Because the model of yaw system is difficult to be set up and some parameters of controller are uncertain. General PID controller is not suit for all operation scope. This paper presents a fuzzy PID controller to deal with the control of yaw system with disturbances and uncertain...
